...He
later holds crowd-drawing lectures on "Health via Magnetism." Due to
his medical background and belief in magnetism, Emerson adopts the name
"Doctor Polaris." He even designs a special costume and mask to wear for
his public appearances.

...A
reformed Emerson travelled to the Earth's magnetic North pole to study
it. Emerson was at the point where the lines of magnetic force converge
when an earthquake plunged him into a deep crevice. At the bottom of the
crevice lay a glowing blue blob. The radiation from the blob altered
Emerson's perceptions...Emerson created a mental duplicate of his evil
alter ego...Once Green Lantern disintegrated the blob, the mental image
of the evil Doctor Polaris faded away. ... Under unknown circumstances,
the catatonic Polaris ends being held in Iraq, but he is rescued by
Hatchet, Heat Wave and Sonar. The trio planned to carry him in the
Aurora Borealis [a.k.a. the aurora polaris] to the magnetic North Pole
for recharge... ...In 2001, Polaris emerges during the Joker's Last
Laugh crisis attempting to take control of the magnetic south pole [aurora australis]
itself...

...Over
the years, the Polaris and Emerson personalities fought for dominance,
until Polaris was approached by the demon Neron. Polaris sold Neron
Emerson's soul in exchange for greater power and being rid of the other,
restraining side of his personality.
